BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 230,736, dated August3, 1880.

Application filed May 12, 1880.

To all whom it may concern:

Be it known that I, ALEXANDER BUoK- MAN, of the city and county ofAlbany, and State of New York, have invented certain new and usefulImprovements in Billing-Presses,

of. which the following is a specification.

My invention relates to that class of balingpresses wherein the materialto be compressed is fed into one end of the pressing-chamber 1c and thefinished bale is ejected therefrom at the opposite end; and it consists,first, in combining with the plunger of the press a togglejoint forimparting motion to the plunger, constructed and arranged as hereindescribed, 1 5 and provided with a detachable sweep for the applicationof animal power thereto, said sweep being adapted to move in oppositedirections, so that when moved in either direction from one extremity ofits movement to the opposite one the plunger will be moved forward toimpart its pressure to the bale and again retracted to put the press incondition for receiving a fresh supply of material; secondly, in themode herein described of brac- 2 5 ing the main center-pin for thetoggle-joint to the press-box; thirdly, in the mode herein described foroperating the side retainers with a positive motion; fourthly, in theimproved retaining device fixed in the top of the pressing- 0 chamber,as herein set forth, for holding the material that is forced into thepressing-chamber, and consisting of a yielding spring-yoke provided witha roller and a serrated bar; fifthly, in the hinged top of thepressing-cham- 5 her, combined with an adjusting-screw for regulatingthe discharge-opening of the press; sixthly, in the improved separatorsherein described provided with spurs fixed in the slatchannels forretaining the bindingslats in 0 place.

My invention also. consists in combining with the pressing-chamber adetachable auxiliarybaling-chamber for receiving the compressed bale asit is ejected from the pressing- 5 chamber, and retaining the baletherein until additional slats and ties are secured thereto, saidauxiliary chamber being constructed and arranged to operate ashereinafter specified.

In the accompanying drawings, which form a part of this specification,and to which ref- (No model.) I

erence is herein made, Figure l is a side elevation of my improved presswith one of the side frames broken away to expose one of my sideretainers; Fig. 2, a plan view of same with the feed-hopper removed;Fig. 3, alon gitudinal sec- 5 5 tion at the line as 00 of Fig. 2; Fig.4, a side elevation of my auxiliary baling-chamber attached to thedischarge end of my press; Fig. 5, a plan view of Fig. 4.; Fig.6, adetached horizontal section of one of my side retainers and thehookpiece of the plunger for giving the said retainer its inwardmovement; Fig. 7, a front elevation of my improved separator; Fig.8, ahorizontal section of Fig. 7 Fig. 9, a detached detail of the serratedbar of the top retainer; and Fig. 10 an enlarged sectional view of thespring-yoke roller, serrated bar, and chamber.

As illustrated in the drawings, A is the box of the press, made at itsreceiving end with solid side walls, and at its discharging end thesides of the compressing-chamber are provided with horizontal slats a,to form suitable openings for facilitating the tying-off of the bales.The'press-box A is secured to the bottom timber, A which forms thebed-piece for the entire press.

A plunger, B, is fitted to receive a reciprocating motion in thepress-box, and it receives the requisite motion from a toggle-joint,composed of the lever 0, arranged to vibrate on the main center-pin, c,and the connecting-bar G, pivoted to the lever O by the pin 0, and tothe plunger B by the pin 1). The jointed end of the lever G is roundedto an arc of a circle of which the pin 0 is the center, and the bar 0 isprovided with an anti-friction roller, 0 arranged to bear against therounded end of the lever.

The outer end of the lever G is provided with a clip, 0 for receivingthe detachable 9o sweep D, (shown as broken off in the drawings,) andwhich may be made of any required length. Said sweep should be fitted atits outer end with a clevis arranged to swing from one side of the sweepto the other, so that the 5 animals that are hitched thereto for thepurpose of working the plunger can, without unhitching, be turned totravel back and forth to move the sweep D from one extremity of itsmovement to the other; and during each I00 movement of said sweep itsouter end will describe nearly a semicircular are, and the parts of thetoggle-joint and the plunger will move as follows: Starting (as aninitial point) with the joint at c at the extremity of its throw outwardat one side of the press, whereby the plunger B is drawn back to theextremity of its outward reciprocation. then, as the center joint of theparts 0 and O is moved inward toward the center line of the press, theplunger B is forced forward to compress the material in the press-box A.This col'npressing movement continues until the pins 0, c, and b of theparts G and 0 are ranged in a direct line, at which point thecompressing mechanism exerts its greatest power; then, as the jointcontinues its movement toward the opposite side of the press, theplunger B is thereby again retracted, so that when the toggle-joint hascompleted this phase of its movement a vacant space is left between theend of the plunger and the compressed material for re ceiving a freshcharge of material, and during the pause in themovement at this point(caused by the time occupied in turning the animals about) ample time isafforded ibrinserting the charge before the connnencement of the reversemovement of the sweep to produce a repetition of the movements of thecompressing mechanism justdescribed. Thus each complete movement of thesweep D carries the parts of the toggle-joint from the point of theirgreatest protrusion at one side of the press to a like point at theopposite side, and causes the plunger B to first move inward to compressthe material and then outward to put the press-box in condition forreceiving a fresh charge; and it will be seen that by this arrangement agreat saving of time is effected as compared with a press ha ing atoggle-joint that only moves up to a center line and then back to itsplace of starting, for the reason that in the latter construction thetime occupied by one of its pauses, while the motion is being reversedwhen the parts of the togglejoint are in a direct line, is entirelylost, while in mine every pause is utilized for replenishing thecharges.

"The main center-pin 0 receives the entire strain arising from thepressure applied by the plunger, and in order to resist this strain thesaid pin is secured at its lower end in the timber A which forms thebed-piece of the press, and at its upper end it is held in position byone orniore detachable braces, E, that are fastened to the head of thecenter pin, and from thence run back and upward to the top of thepress-box, and are there hooked over and bolted to the cross-tie c,which engages behind the uprights at the front end of the press-box. Bythis mode of bracing the main center-pin to the press ample room isprovided beneath the braces for the movements of the toggle-joint, andthe center-pin and press-box are held together in such manner thatneither of them can spring away from the other when the strain isapplied.

By making the braces E detachable I am enabled to make a shortpress-box, and while the press-box and center-pin are thereby securedtogether, so that they afford mutual support to ca eh other, readyaccessmay be obtained to the underlying parts for the purpose of examinationand repair by simply removing the braces from their place.

A feed-hopper, F, is fitted over the opening formed in the top of thepress-box for introducing the hay or other material into the press.

In the top of the compressing or baling chamber A, just behind thehopper, there is a de 'ice for retaining the charges of material thatare forced into the-balingchamber. Said device consists of theyieldingspring-yoke G, pivoted to the sides of the chamber and providedwith the roller g, arranged to rotate in the front end of said yoke, andwith a spring, g, arranged at the opposite end oftheyoketo depress theroller 9, but permitting said roller to rise when occasion requires. Aserrated cross-bar, g is placed immediately behind the roller g, and issecured to the rear end of the springyoke by the bar in such manner thatthe said cross-bar can rise and fall independently ofany movement of thespring-yoke. A spring, 9 presses down the cross-bar 9 but permits it torise when needed. The teeth of the crossbar g project below the-lowerside of the roller g, and are bent backward so as to permit the materialto pass freely under them when the plunger forces it into thebaling-chamber; but on the return movement of the plunger the bentpoints of the teeth prevent the material from following the plunger. Achamber, a, formed by chamfering off the end of the top piece, A of thebaling-chamber. immediately behind the serrated cross-bar permits thematerial to expand upward therein, and renders essential aid to saidcross-bar in retaining the material from following the plunger on itsreturn stroke.

The operation of this retaining device. is as follows: The surplusmaterial that usually overlaps the top of the plunger is forced by theinward movement of the plunger beneath the roller 1 and serratedcross-bar 9 both of which rise, as hereinbefore described, to allow theexcessive quantity to pass into the balingchamber; but as the plungermoves outward on its return stroke the hooked teeth of the cross-barengage in the material and prevent IIO it from following the plunger outof the balingchamber.

In recesses at each side of the baling-chamber the side retainers H arearranged to slide on the studs lb. Said retainers are provided on theirinner faces with the projecting angles h and on their backs with theprojecting angle 1L2. All of said angles have their inclined facesarranged in relation to the plunger B as shown in Fig. 6. Thearrangement of said retainers is such that as the material is forcedinto the baling-chamber it presses against the inclined faces of theangles h, (which are then projecting into the baling-cham ber,) andforces the retainers, by a positive movement, back into their recesses.Then as the plunger B continues its inward movement the hook-pieces I),attached to each side of said plunger, engage with the angles 1L therebymoving the retainers H inward by a positive motion and forcing theangles h to enter the recesses b formed in the sides of the plunger B,so that when the plunger is drawn back the angles h will project intothe baling-chamber in such manner as to retain the compressed materialin place against any resilient tendency it may possess.

The top piece, A of the baling-chamber is divided transversely, and thetwo parts are jointed together by one or more hinges, a Over therearmost part an adj Listing-screw, I, is fixed for the purpose ofadjusting the deflection of said part to regulate the size of thedischarge-opening in the rear end of the balin g-chamber, and therebyproduce the required resistance to the passage of each bale through saidopening to effect the proper degree of compression for the bales.

The separators J are used for the purpose of dividing the bales fromeach other. They are provided with channels j for receiving thebindingslats that are secured on the ends of each bale. Each of saidchannels is provided with sharp spursj, on which the binding-slats areimpaled before the separators are put in the press. The grooves j areformed in the separators crosswise of the slatchannels for the purposeof passing the bale-ties over and behind the binding-slats in tying offthe bales.

The auxiliary baling-chamber K is made with open ends corresponding insize to the transverse section of the baling-chamber of the press. It iscomposed of the bottom piece, It, end frames, it, top piece, W, and sidedoors, k The top piece, k is loosely attached to the end frames, and isadapted to an up-and-down movement on the guide-pins L when the doors kare open 5 but when the said doors are closed the lugs M, secured to thetops of the doors, engage over the top piece, 79, and hold said toppiece down flush with the top of the end openings. The bottom and toppieces of the said chamber are provided with grooves it, through whichthe ties for fastening the side bindingslats are passed. The doors k areprovided with channels 7& for receiving the side binding-slats for thebale, and the said slats are impaled on thesharp spurs k fixed in thechannels k and are held thereby while the slats are bound to the baleand until the doors k are opened.

The chamber K is detachable from the press, and is only used whenlongitudinal slats are required on the bales, and it is then secured tothe press by the fastenings N, which en gage with the studs n, fixed inthe rear end of the press.

The operation of this part of my invention is as follows: The sidebinding-slats are .secured, as described, in the channels 75", and thedoors k are closed and secured by the fastenings 0. Then the bale, whichhas been previously compressed and bound endwise the baling-chamber ofthe press, is forced out of the discharge-openings of the press into theauxiliary chamber, where it is retained until the transverse ties arefastened around the bale. The doors 7: are then thrown open to releasethetop piece, It, and leave the bale free, so that it can be readilythrown out of the chamber through one of the door-openings at the sideof said chamber. side slats is placed in the chamber its, the

doors k are closed, and the chamber is again in condition for arepetition of the operation just described.

It is obvious that the arrangement of the loose top piece, k and doors kprovided with lugs M, to secure the said top piece in place when thedoors are'closed, as hereinbefore (lescribed, may be applied to thebaling-chamber of a press, whether such baling-cha-mber is an integralpart of the press or is made detachable therefrom.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- I. In a baIing-preSs, the combination,with the press-box A and reciprocating plunger B, of a double-actin gtoggle'joint 'for imparting motion to said plunger, composed of thelever 0, arranged to vibrate on the main centerpin 0, and theconnecting-bar U, pivoted to the plunger B and lever O, as described,and the sweep D, the said toggle-joint being adapted to move in suchmanner that its knucklejoint at 0 will at each alternate motion protrudeat opposite sides of the press, as herein specified.

2. In a baling-press, the combination, with the center-pin c for theplunger-moving mechanism, having its lower end secured to the bed of thepress, of one or more detachable braces, E, secured to the head of thepin 0 and to the upper side of the press-box A, as and for the purposeherein specified.

3. In a baling-press, the combination, with the baling-chamber of thepress and the plunger B, of the retaining device, consisting of thespring-yoke G, provided with the roller 9 and serrated crossbar g andthe springs g and g, as herein specified.

4. The retainers H, provided with anglepieces h and W, in combinationwith the plunger B, provided with hook-pieces b, adapted to co-operatewith the angle-pieces [L2 and move the retainers H with a positivemotion, as herein specified.

5. Ina baling-press, the combination, with Another set of the thereciprocating plunger B, of a toggle-joint composed of the lever 0,arranged to vibrate on the centei pin c, and connecting-bar O, pivotedto the plunger B and lever G, as here- 5 in described, and thedetachable sweep D,

adapted to connect to the lever O, substantially as herein specified.

6. The separators J, having slatchaunels j, provided with spurs j, andthe tie-grooves i IO as and for the purpose specified.

7. The detachable auxiliary baliug-ehauiber K, adapted to receive acompressed and tied bale from a baliug-press, in the manner and for thepurpose herein specified.
